LIQUID-MEASURING DEVICE;

, Application filed July 14, 1 922. Serial No. 574,930.

T 0 all whom it may concern .-Be it known that I, OLIVER P. M. PFAF.-.

FENBERGEma citizen oftheUnited' States, and a resident of Indianapolis, county of Marion and State of Indiana, have invented a certain new and useful Liquid-Measuring Device; and I do hereby declare that the following is a full, clear, and exact descrip tion thereof, reference-"being hadto the accompanying drawings, in which like numerals refer to-like parts. V T

This invention relates to a medicine measuring and dispensing device for use with medicine containers.

The chief object of the invention is to provide a device which will not only prevent the free flow of liquid from a container to a dispensing mouthpiece and permit such free flow when desired, but which'is also adapted to measure the liquid dispensed.

.. An equallyimportant object of the invenv tion is to construct the device in such a manner that the parts are readily detachable from each'other for cleansing purposes.

The chief features of the invention,'in addition to the accomplishment of the foregoing objects, consists in the provision of a mouthpiece which is detachably associated .with'the measuring device proper or an'elbow extension.

. Another feature of the invention consists of a cap which is detachably assoclated with v the discharge end of the. mouthpiece.

I cap. Fig. 2 is an enlarged longitudinal sectional view of the measuring device with the valves in the filling position and provided with a directly connected mouthpiece. Fig. 3 is a similar view of the same device with the valves in the dispensing position and an elbow extension for the mouthpiece. Fig. 4 is a similar view of the device withboth valves in the open position for constant liquid flow. Fig. 5 is a sectional view of the connects the tubular end 16 with the chamber forming end 18. The intermediate 'por several pallts 2f thedeliile inidetac'hed rela' tion preparatory to cleansing;

an the drawings 10 indicates a bottle provlded with a neck 1 1.and a mouth 12 adapted to receive a coil; 13 wl1ich supports a flanged tube 14 having the flange 15f The flanged tube 11 is adapted to telescopically support one end ofa tubular member 17. The tubu lar member 17 at itsopposite endis recessed and provides a chamber 18. A channel 19 tion through which the channel 19 extends is transversely recessed as'at 20 to support a rotatable valve 21 having the controlling portion 22- which controls the channel 19. Free flow of liquid from thebottlelO through the channel19i'nto the chamber 18 is controlled by the valve 21. The valve 21 is pro vided with a stem associated with which is a lever handle 23. This; valve construction presents a rectangularor flat side for engagement by a spring member 24 secured to the'bodv 17 by suitable means, such as the screw bolt 25; The'spring 24: is adapted to maintain the valve 21 inthe predetermined position, whether it be fullyopened or fully closed, or in an intermediate-position.

A tubular member 26 at one end is prowhich is telescopically associated with the chamber forming portion 18 ofthemember 17. The other end of the tubular member 26. :is provided with a portion27 adapted to re ceive the supporting end of the mouthpiece 28. The mouthpiece 28 is provided'with a relatively flat discharge portion 29, and said mouthpiece is adapted to be closed for sanitary reasons by a cap 30. forming portion 27 discharges into the 'mouthpiece128by means of the channel 31.

Transversely of the channel 31 is a recess 32' adapted to receive a. valve member 33. The valve member 33 isprovided with a stem 34, and concentric with the stem' 34 is a spring 35. The spring 35 tends to normall'yseat the valve'33in the closed position,thereby v closing the communication through the c'hannel 31. A suitable retaining member '36, retains the spring within the transversely ex tending. opening and slidably supports the stem 34;. The stem 34ecarries a transverse pin 37. Positioned upon and preferably integral'with thetubular portion-17 is a pair of'ears 38 which support a pin 39. The pin vided with a chamber forming portion 27 l The chamber the pin 37 on the valve stem 34. Pivotal.

. As shown clearly in Fig; 5, the chamber forming'portionsfl'? and18 are detachably associated together, and said chamber forming ,portionsiare adapted toreceive one: or more volumetr cmembers 43 here1n shown in the form of a ball. The volume-ct the 7 combined chambers 18 and'27 is preferably such that it is adapted to receive one table spoonful of liquid, and the volume of the ball is preferably equal to that of a teaspoonful of liquid, sothat the presence of the ball withinthe combined chamber reduces the'capacity of the chamber from a tablespoonful to a, teaspoonful. Other 'forms or volumetric reducers may be providedand the nun1ber;and size. thereof may be reduced or increased as desired. 7

5 shows the device disassembled, so that veachand every part of the device may be readily cleansed. a

. In Fig. 3 there'is illustrated an elbow eX- tension tube 12 8 which terminates in a formatio'nsimilar to the .end ofthe tube 27 so that the extension may receive the tubular member 28 shown in Fig. 2-, when desired. rom the foregoing it will be noted that the levers 23 and 4ilhave their actuating portions adjacent each other and very close to.the ;.inlet endof the device, so that one hand may grasp the neck of-the bottle and support the same and the fingers may manipulate either or both of the levers for liquid control by the device, leaving the other, hand free for handling the patient if necessary.

The invention claimed is: c

I 1. In a liquidjmeasuring device, a tubular channel, including a measuring chamber, a plurality of valves for controlling said channelifor measuring the flow of liquid, said chamber being arranged to provide access thereto, and a volumetric reducer receivable bysaid chamber for. reducing I purposes, but permitting thefiow of liquid through saidchamber i 2. Inaknock-down liquidmeasuring de- -vice, the combination of a lurality of tubular members detachably connected together and. formed so as, to p ovide a measuring chamber, a valve positioned in one" of said ,tubular members, and controlling. tlieentrance to the ehamber, another valvecontrolling said'chamber and supported by anotherztubular member, and spring means associated with eachva'lveffor maintaining said valvein a. predetermined. position;

In aknoclr-down liquid measuring device, the combination of a plurality of tubular members detaehaibly connected 7 together and formedso as'to provide ameasuring chamber, a valve'p'ositioned .in oneflof said. tubular members and controlling the en trance to the chamber, another valve con trolling said chamber'and. supported by another tubular member, a lever detachably supported by one of said elements and adapted to, engage and operate the valve in the other element. c

e. In a knock-down liquid measuring de vice, the combination'of aplurality of tubu-v ii I larmembers detachablyL connected together and formed so as to providea measuring chamber, a valve positioned in one of :said tubular members and controlling theentrance to the chamber, another valve controlling said chamber and supported by another tubular member, a lever detachably supported by one off said elements-and adapted toiengage and operate the valvle'in the other element, and spring means asso- J ciated witheach valve for maintainingsaid valve 1n a predetermined position.
